Hi,
I’m sorry to hear about your difficulties with Tobii devices. If the sales team isn’t responding to your emails, try contacting them through alternative channels like their support forums, social media, or local distributors. The one-month free unlock mentioned in their materials should be genuine, so ensure you’re contacting the correct email address with all necessary information. Additionally, you might find help in online communities where researchers share alternative methods for collecting gaze data. Document your attempts to contact them, as this can help if you need to escalate the issue. Good luck!
